Sets the triangle list for the sub-mesh.
A sub-mesh represents a list of triangles that are rendered using a single Material. When the Mesh is used with a Renderer that has multiple materials, you should ensure that there is one sub-mesh per Material.

The baseVertex argument can be used to achieve meshes that are larger than 65535 vertices while using 16 bit index buffers,
as long as each sub-mesh fits within its own 65535 vertex area. For example, if the index buffer that is passed to SetTriangles
contains indices 10,11,12 and baseVertex is set to 100000, then effectively vertices 100010, 100011 and 100012 will be
used for rendering.
Note that meshes use 16-bit indexFormat by default, i.e. maximum value supported in the index buffer is 65535 (even when using @int[]@ input data). In order to use larger index buffer values, you should first set the indexFormat to IndexFormat.UInt32.

Sets the triangle list of the Mesh, using a part of the input array.
This method behaves as if you called SetTriangles with an array that is a slice of the whole array, starting at trianglesStart index and being of a given trianglesLength length. The resulting Mesh has trianglesLength amount of vertices. Resulting sub-mesh will have trianglesLength/3 amount of triangles.
